The awful truth about this is that the JWs love to use the following line of reasoning both at the door and, worse yet, in court cases:
"Well, if your really want to know what a group is like you would ask them, wouldn't you? If you really want to know what Jehovah's Witnesses are like -- just ask us!"
That's just downright idiotic. By that line of reasoning someone who really wanted to get to know a candidate for political office should just listen to their ads. The flaw in that thinking is so obvious it doesn't even deserve to be said.
Of course, it would be incorrect to judge a group -- the JWs or others -- simply by the writings of their critics. The thing to do is get all sides of the matter -- critics, the group itself and non-committed third parties. Why doesn't the WT advocate that type of investigation? Again, I think you already know why
